When dealing with letting agents you should be aware in advance what the likely charges during the tenancy will be.
Believe it or not some agents even go so far as to charge you to provide a reference to your next letting agent/mortgage company when you leave at the end of the tenancy! Other charges include check-in and check-out fees. Brookdale do not charge for these.
1st applicant £280 inc. VAT
2nd applicant £140 inc. VAT
3rd applicant £140 inc. VAT
The only other charge during your tenancy is for renewal of contract which is £40 plus VAT = £48. It is your choice if you wish to renew the contract.
